Birthday Calculator
Find the day you were born, your zodiac sign and next birthday.
A birthday calculator does more than tell you how old someone is. It calculates your exact age in years, months, weeks, days, hours, minutes, and seconds — and tells you the day of the week you were born, how many days until your next birthday, your birthstone, your zodiac sign, and your Chinese zodiac animal. Whether for curiosity, a milestone celebration, or filling in an age-based form accurately, this calculator gives you every detail about any birth date.
📋 How to Use This Calculator
Enter the birth date using the date picker or type it in DD/MM/YYYY format. The calculator instantly shows the exact age in multiple units, the day of the week of birth, days remaining until the next birthday, and the corresponding zodiac signs. The age calculation accounts for leap years precisely — so a person born on February 29 in a leap year has their age correctly calculated for all non-leap years.
💡 Key Facts & Information
Age calculation seems simple but has several edge cases. February 29 birthdays only occur every 4 years (leap years divisible by 4, except centuries not divisible by 400). Legal age in India is 18 for voting, driving (two-wheeler), and entering contracts. Minimum age for driving a car is 18; for heavy vehicles, 20. Retirement age for central government employees is 60. Senior citizen benefits in India begin at 60, with "super senior citizen" tax benefits from age 80. The Indian zodiac (Jyotisha) differs from Western astrology — it is sidereal (star-based) rather than tropical (sun-based), placing signs approximately 23 days earlier.
